[PATCH 1/2] net: systemport: Remove unused txchk accessors
Posted by Florian Fainelli 1 month, 1 week ago
Vladimir reported the following warning with clang-16 and W=1:

warning: unused function 'txchk_readl' [-Wunused-function]
BCM_SYSPORT_IO_MACRO(txchk, SYS_PORT_TXCHK_OFFSET);
note: expanded from macro 'BCM_SYSPORT_IO_MACRO'

warning: unused function 'txchk_writel' [-Wunused-function]
note: expanded from macro 'BCM_SYSPORT_IO_MACRO'

warning: unused function 'tbuf_readl' [-Wunused-function]
BCM_SYSPORT_IO_MACRO(tbuf, SYS_PORT_TBUF_OFFSET);
note: expanded from macro 'BCM_SYSPORT_IO_MACRO'

warning: unused function 'tbuf_writel' [-Wunused-function]
note: expanded from macro 'BCM_SYSPORT_IO_MACRO'

The TXCHK block is not being accessed, remove the IO macros used to
access this block. No functional impact.

Forgot to remove the tbuf accessor here as well, will post again in 24hrs.

I mean the warnings do say that the tbuf macros are unused too, yet you
only remove txchk? I did ask yesterday if that should also be deleted,
and with it the other unused transmit buffer macros?
